About this Research Topic
Scientific research on cold-adapted microorganisms (specifically polar microbes) is of great interest, since Arctic and Antarctic regions harbor diverse and active populations of microorganisms. However, these microorganisms are subject to impacts of environmental perturbations. For example, climate change will modulate the distribution and activity of many cyanobacteria and algal species in polar environments that contribute significantly to global carbon fixation and oxygen production. Moreover, many microorganisms that have remained frozen for thousands of years can revive their metabolic activity and re-join the modern microbial community.
For survival in freezing environments, polar microorganisms have established specific regulatory mechanisms which are now being challenged by new, rapidly changing environmental conditions. Remarkable progress has been made to uncover microbial adaptation to anthropogenic activities such as high irradiance, nutritional deprivation, UV-B radiation, heat, cold, desiccation, and heavy metals. Studies have enabled a basic understanding of gene regulatory pathways for morphological, physiological, metabolic, and genetic adaptations to various environmental stresses. To further elucidate physiological adaptation mechanisms and molecular diversity in polar regions, this Research Topic is focused on microbes in polar regions, looking at their biodiversity, ecological adaptations, the impact of climate change on their lifestyles, and biotechnological application of microbes for a sustainable future.
Topics of interest include, but are not limited to:
• Microbial diversity and their roles in polar ecosystems, and impact of climate change
• Microbial physiological adaptations to polar regions giving a molecular understanding
• Cutting-edge research to explore microbial diversity and acclimation in polar and deep oceans
• Biotechnological applications of polar microbes such as bioremediation, agricultural sustainability etc.
We accept Original Research and Review articles related to microbial adaptations to extreme environments in polar regions.
